Diesel fuel emulsion

Abstract

The present invention relates to a fuel for reducing the noxiousness of exhaust gases, particularly for internal-combustion engines. The fuel has the peculiarity of comprising a mixture of a combustible fuel with 10 to 42% water by weight with respect to the combustible fuel, with the addition of a lubricating antifreeze activator in an amount comprised between 0.5 and 2% by weight of the amount of combustible fuel. The mixture is atomized and stabilized by means of a turbine transducer which provides an electro-magneto-mechanical action, subjecting the mixture, in succession, to positive-pressure actions alternated with negative-pressure actions at high frequency.

I claim: 
     
       1. A method of preparing a diesel fuel composition in the form of a stable emulsion, comprising the steps of: a. preparing a mixture of an amount of diesel fuel, an amount of water equal to from 10 to 42% by weight of said amount of fuel, and an amount of lubricating antifreeze activator equal to from 0.5 to 2.0% by weight of said amount of fuel, by pouring the water and the activator in the diesel fuel, said lubricating antifreeze activator being selected from the group consisting in sorbitol mono-oleate, sorbitan mono-oleate and their mixtures;   b. passing said mixture through a turbine transducer which provides an electro-magneto-mechanical action by subjecting said mixture, in succession, to positive-pressure actions alternated with negative-pressure actions at high frequency, thereby obtaining a stable emulsion.
